1946 S-over-D: The Helen Keller Perspective

I promised myself I wouldn't get any more sucked in to my dad's coin collection, but I noticed he'd sorted a bunch of 1946S pennies, and I made the mistake of looking them up and learning out about the S-over-D overpunch, and my eyesight's horrible, so I had the bright idea of shooting them with my iPhone on a tripod plus a flashlight, but I still can't freaking tell, and am not super desperate for the thirty bucks or whatever even if I got lucky, but I've gone this far so I may as well see it through.

Photos #1 and #2 are the one that I think's the best candidate, but what do I know? The same coin is top/left in photo #3.

I used to use a Pac-Sci stereomicroscope with optical zoom and built-in halogen lighting with dimmer, but I ended up selling it for lack of space in my latest residence. Here are some examples of close-ups I took with it.

If I ever decided to buy another stereomicroscope, I would make sure it had the same capabilities plus a dedicated eyepiece (trinocular) for the camera. ~ Chris
